Yep, it's the first time many (including myself) have fully used the Bitcoin network. Sure, we've used bitcoin (the money), and maybe we ran a node and verified and relayed transactions but it's the first time many of us have actually had a say in what actually gets put on-chain.
Pretty awesome stuff.
And loads of thanks to the folks making this possible.
